Power Supply Compatibility

Hey people : ) Just getting this HP P6240F Pavilion and I wanted to replace the built in intel graphics with this HIS Radeon HD 5750. In order to do this I had to up the power supply so after a bit of searching I found one, but I'm not sure if it will fit in my case!. I'm not sure how hard it is for you to find out but if you could do that for me and also check if the graphics card would fit I'd appreciate it VERY VERY much. I have the links below for all the products. Thanks in advance.
